We don’t have unlimited time for our beauty routines and we know you don’t either. Lash extensions fall into the category of things we rarely have time for but often wish we did. Since most of us, including Birchbox editor Lorelei, consider mascara a makeup-must, we’re obsessed with ModelCo’s FIBRE LASH Brush on Lashes, which includes both a black extension mascara and lash fibers. It’s lengthening without looking unnatural and washes off easily.
